We prefer relatively the smaller expedition capable type ships. Have voyaged now for over 400 nights. Used HAL and Princess until we discovered Regent. No problem with HAL and Princess but Regent is superior in the majority of categories.
This trip was Miami to Miami,13 ports visited, 6 on the Amazon River. Very educational and enjoyable. This is our second cruise on the Navigator and third on Regent. Very good ship for exploration style voyages. Regent has made a few modifications to the ship since they acquired it. All for the better. Some complain of the vibration but it actually isn't bad at all, only in the stern during departures. Regent is the only line we have been on where the smell of sewage on its ships isn't detectable at times in various locations.
The public space per passenger is about the highest in the industry and the ratio of crew to passengers is also on the top of the list.
We particularly like the cabins. They are very spacious, at least in the deluxe suite and penthouse suite accommodations. A smaller balcony suite has 356 sq. feet of space, compared to slightly over 200 on many other ships. We have had a separate bath and walk in shower in the spacious bathrooms every time. Same goes for the walk in closets which are about as large as standard cabin bathrooms.
Food was excellent and we never have been delayed for meals at any time, we usually eat dinner at table for two in the man dining room. Sure nice to not be hog tied to a traditional dining environment where one is relegated to dine with "luck of the draw" random dinner companions, night after night. The specialty restaurant, "Prime 7", is an excellent intimate quality culinary experience. Only problem is there are not enough tables for two. We recommend they restrict seating at tables for 4 & 6 to parties already formed up prior to dinner. No seating with random companions should be made. Part of the reason for this is there is no extra charge for the premium dining rooms on Regent. Therefore some show up because they believe they must take advantage of a perk, regardless whether they are in a foul mood and improperly dressed.
We visited St. Barts, St Lucia, Devils Island, Trinidad, Santarem, Manaus, Parintins, Barbados and Antiqua--Shore excursions were all excellent but we did prefer some ports much more than others. Parintins was a little Amazon River village which we had to walk to from the beach, population 100, which symbolized best the theme of the voyage and gave us the a real appreciation of life on the Amazon.
No nickel and dimeing with Regent. Your initial payment covers almost everything including liquor (fine selection of red wines on board) as well as the best shore excursions we have experienced.
